LOUIS STEETS, OF NElV YORK, N. Y.

TUNING-HAMMER.

SPECIFICATION forming part of Letters Patent No. 342,051, dated May 18,1886.

Application filed May 1, 1885. Serial No. 164,077. (No model.)

To all whom it may concern.-

Be it known that I, LoUIs STEETS, of the city, county, and State of NewYork, have invented certain new and useful Improvements inTuning-Hammers, of which the i'ollowing is a specification.

This invention has reference to an improved tuning-hammer, by which thetuning-pins of grand, square, and upright pianos can be convenientlyoperated for tuning; and the invention consists of a tuning-hammer theshank of which is provided at its outer end with ahead having a squarerecess and a tuningsocket with a square shank, which latter is guided insaid head and adjusted igher or lower in the same, so as to readilyreach the tuning pins.

In the accompanying drawings,Figure 1 represents a vertical longitudinalsection of my improved tuning-hammer. Fig. 2 is a top view 5 Fig. 3, avertical transverse section on line a; m, Fig. 1. Fig. 4 is a detailsection showing a modified construction of the adjustable tuning-socket,and Fig. 5 is a detail section showing the tuning-socket detached andapplied to a common handle.

Similar letters of reference indicate corresponding parts. A

A in the drawings represents the hollow handle of my improvedtuning-hammer, which handle guides a longitudinally-grooved shank, B,having an enlarged circular head, B, for the shank O of thetuning-socket O. The shank B is capable of adjustment in the handle A bymeans of a set-screw, a, that passes through a metallic ferrule, A, atthe end of the handle and engages the longitudinal groove of the shankB. The enlarged head B has a square recess that is slightly inclinedtoward the axis of the shank B, said recess serving to support thesquare shank O of the tuningsocket O. The socket O can be adjustedhigher or lower in the recessed head B, according to the position of thetuning-pins to be operated upon.

\Vhen the shank O has been adjusted to its position in the head B, it isrigidly secured to the head by turning the same and screwing up itsinteriorly-threaded socket B on the threaded outer end of the shank B,as shown in Fig. 1, whereby the shank B presses on the shank O andclamps the same rigidly to the recessed head B.

In place of attaching the head B by a screwsocket, B to the shank B, itmay be made integral with the shank B, in which case the shank of thesocket C is secured in position by a clamp-screw, d, as shown in Fig. 4,or by any other suitable clamping device.

\Vhen replacing a broken string by a new one, the tuning'pin is turnedby the socket C, the shank of which is inserted into a socket of acommon handle, D, as shown in Fig. 5. hen the string has been wound upsufficiently on the tuning-pin, the tuning of the same is completed byusing the socket O in connection with the shank B and handle A, as bythe greater leverage of the same greater force can be exerted on thepin.

By means of the adjustability of the main shank B and of thesocket-shank O the tuninghammer may be readily adjusted to diiferentlengths and depths, so as to reach the tuningpins with great facility,whatever be their position. The adjustment is accomplished quickly andreliably without the use ofascrewdriver, and thereby the work of tuningexpedited and facilitated.

Having thus described my invention, I claim as new and desire to secureby Letters Patent The combination of a hollow handle, a main shanksecured adjustably to said handle, and having a threaded outer end, anenlarged and recessed head having an adjustable screwsocket, and atuning-socket having a square shank secured adj ustably to said head,substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed myname in presence of two subscribing witnesses.

LOUIS STEETS.
